Curses

This week we concluded the prologue of Sefer Chofetz Chaim it concludes with 3 (really 4) curses in the Torah associated with lashon hara which an be found in the Torah portion of Ki Savo.
 1. ארור מכה ראהו בסתר One is cursed for hitting his friend in a hidden place which the Sifri and Rashi on Chumash say refers to speaking lashon hara for he doesn’t physically strike his friend on his body but his speech effects the other’s emotions or heart. 
2. ארור משגה עור בדרך This curse is for giving people bad advice on purpose for one’s own benefit but it is also a curse for leading others to sin like in this case where the speaker of loshon hara is causing the listener to potentially sin if they want to listen and the listeners cause the speaker to sin by encouraging him to speak loshon hara through showing they want to hear what he has to say. 
3. ארור אשר לא יקים את דברי התורה הזאת לעשות אותם Hashem curses those who don’t take his mitzvos seriously and don’t accept upon themselves to make at least some effort to adhere to them. Even if he doesn’t care about one mitzva and habitually transgresses it even if he observes everything else he is what’s called a mumar for one thing. The issue is a lack of care to try to guard oneself from the sin not the transgression itself because it shows a lack of care to follow Hashem’s command. 
4. ארור מקלה אביו ואמו If one speaks lashon hara about his parents there is an addition curse.One of the ramifications of being cursed is being excommunicated in Heaven which is pretty scary. 
In conclusion The Chofetz Chaim said that this prologue should be reviewed over and over again because it might be the best deterrent out of anything else he writes, from speaking lashon hara.
